FWIW, I installed the Polish 65mm pulley about two weeks ago. The factory pulley had 4 shims behind it. Code 3 specifies a .2mm to .3mm gap between the SC clutch and the back side of the pulley. Initially, mine required removing ALL those shims to get a gap just over .2mm (it was around .22mm or so).
I checked it yesterday, and the gap was now UNDER .2mm!! (The SC still spun freely with the engine off, and I could stop the SC clutch with my bare hands when the engine was running, but I didnt like that the feeler gauge was such a tight fit between the clutch and back of the pulley)).
As a precaution, I installed 1 shim (they're .1mm thick) and now I have slightly less than a .3mm gap, maybe .28mm or so. So far, the SC spins freely with the car off, and the car runs and drives very normally).
So Im wondering (since you have the same pulley, bbsrt6) if maybe you have too MUCH gap, causing the SC to engage abruptly? It certainly would explain the torque shove you describe if the SC is not engaging around 1200rpm or so.
(You didnt mention if the car is making "normal SRT power" under 3000rpm).
Just a thought from a Xfire noob.
